    Abstract

    Acrylic maintenance coatings are applied over aged organic asphalt shingle and built-up roofs and allowed to weather for 6–10 years. Test cut samples are analyzed chemically and via optical and scanning electron microscopy techniques and compared to uncoated areas subject to the same weathering. A mechanism for explaining weathering of asphaltic roofing materials is proposed, and the effect of acrylic maintenance coatings in reducing weathering is also clearly elucidated and documented.
